The invention relates to the technical field of railway vehicles, and provides a central traction device, a bogie and a railway vehicle, and the central traction device comprises a traction beam, a pin sleeve, a central pin and a connecting rod. Wherein the traction beam is provided with a mounting channel along the height direction, and the outer surface of the traction beam is provided with a connecting part. The pin sleeve is installed in the installation channel, a pin hole and two free gaps are formed in the pin sleeve in the height direction, and the two free gaps are located on the two sides of the pin sleeve respectively in the width direction of the railway vehicle. The center pin is installed in the pin hole. One end of the connecting rod is connected with the connecting part, and the other end is suitable for being connected to the framework. Redundancy of structural parts of the central traction device can be avoided, and light weight is achieved under the condition that transverse, vertical and longitudinal functions are kept unchanged.

    本发明涉及轨道车辆技术领域,提供一种中央牵引装置、转向架及轨道车辆,该中央牵引装置包括牵引梁、销套、中心销和连杆。其中,牵引梁沿高度方向构造有安装通道,牵引梁的外表面构造有连接部。销套安装于安装通道,销套内沿高度方向构造有销孔和两个自由间隙,沿轨道车辆宽度方向,两个自由间隙分别位于销套的两侧。中心销安装于销孔。连杆的一端与连接部相连,连杆的另一端适于连接于构架。能避免中央牵引装置结构件的冗余,在保留横向、垂向和纵向功能不变的情况下实现轻量化。
